Typo on my part. It maintains compatibility with what it used to mean, 
so it's good.

I wonder if we want *three* forms available directly in the schema. Can 
we condense it back down to two somehow? Could we possibly remove the 
list-less form?

(The less forms we have, the easier it is to offer e.g. intellisense 
plugins for vscode and things of that nature, which is something I have 
an interest in to improve the usability of the generator for 
contributors who are less invested in the QAPI subsystem.)
